SYRlNGE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 589,017, dated August31, 1897. Application filed January 11, 1897. Serial No. 618,693. (Nomodel.)

To all whom it may concern:

Be it known that 1, ANDREW MOTERNEN, of Andover, county of Essex, Stateof Massachusetts, have invented an Improvement in Syringe-Nozzles, ofwhich the following description, in connection with the accompanyingdrawings, is a specification, like letters and figures on the drawingsrepresenting like parts.

This invention relates to improvements in nozzles for vaginal syringesof that kind having a globular deliverythat is to say, a nozzle whereinthe parts are so constructed and arranged that the water will bedelivered in a more or less globular or ball-shaped spray or film.globular or ball-shaped spray or film it may be forced in advance of theend of the nozzle to the inner end of the vagina and about the mouth andneck of the womb without entering the uterine cavity.

In accordance with this invention a hardrubber pipe is formed at itsextremity with an externally-screw-threaded perforated end portion, fromwhich projects centrally a stem surmounted bya flattened head, and asleeve or end piece having a hole through it larger in diameter than thediameter of said head is adapted to be screwed onto the pipe, inclosingits perforated end, its stem, and head, and the parts are so disposedwith relation to each other that a more or less globular delivery isinsured.

Figure 1 shows in side elevation a syringenozzle embodying thisinvention; Fig. 2, a similar elevation and partial vertical section ofsaid nozzle.

The pipe at, of hard rubber or other material and of suitable size andlength, is formed at its outer extremity with a projecting end portiona, havingan exterior screw-thread 2 and several perforations 3. throughit, and projecting centrally from said end portion a is a stem asurmounted by a flattened head a The projecting end portion a is madeless in diameter than the external diameter of the outer extremity ofthe pipe, so that a flat shoulder or seat is formed or provided at saidend'around the baseof the said projecting end portion. The stem a ismade quite short and small in diameter, and the head is formed with aconvex outer face and a more or less frusto-conical or beveled underface, as shown particularly in Fig. 2.

A sleeve or By delivering the liquid in such a.

end piece 7), of any suitable size and formed with an internalscrew-thread and also with a hole through it at least a little larger indiameter than the diameter of the head a is adapted to be screwed ontothe projecting end portion of the end of the pipe, it at such timeinclosing said end portion, its stem a projecting therefrom, and thehead a The sleeve or end piece I? is preferably more or less chamberedinteriorly, as shown in Fig. 2, at that portion thereof which surroundsthe stem a to thus provide at such point a larger chamber, and also theouter end of said sleeve or end piece is dished or countersunk slightly,so that its most contracted part shall terminate just below the widestdiameter of the head a when said cap is screwed on so far as to abutagainst the shoulder or seat at the end of the pipe a, formed orprovided around the base of said projecting end portion.

The parts when assembled as shown in Fig. 2 are so disposed that aglobular delivery is insured.

The particular construction of nozzle herein shown and which'forms thesubject-matter of this invention is important on account of itssimplicity and because it can be so readily taken apart and cleansed andthereafter easily assembled and adjusted.

I claim-- A syringe-nozzle, consisting of apipe a, having at itsextremitya perforated end portion or externally screw-threaded andprovided with a central projecting stem a surmounted by a head a andhaving a seat at the base of said end portion, and aninternally-screwthreaded sleeve or end piece I) having a hole through itlarger in diameter than the diameter of the head a and adapted to bescrewed onto the pipe at abutting against said seat, and inclosing theperforated end portion, the stem and head, the partsbeing so disposedwith relation to each other that the water is delivered in a globular orball-shaped spray or film, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ANDREW MOTERNEN.
